comment Is it worth separating your vo2 max wattage's on the flat and hill climbs in order to provide clearer goals during training?
Excellent. Thanks for the PF/PV plots. This is very helpful. You can use the "find interval" tool to zoom in on the "peak" 5 minute power for each of those rides (then highlight the peak interval and look at PF/PV again), but I suspect that we already have enough info. For neuromuscular reasons many riders have an easier time generating high pedal force at low crank inertial load, such as usually occurs during a steep hill climb (you can see the difference at around 1 m/s (~60 rpm) and 350 N). If you can supplement with those two plots I may be able to give a fuller answer.

Before giving an answer, we'd need more information, especially two things: 1) how are you measuring these maximums; and 2) have you looked at your pedal force/pedal speed, especially with gradient of the slope? Depending on your answers, you may not need to "separate" your goals.

comment Is there a cycling equivalent to Naismith's rule
VAM was coined by the Italian Michele Ferrari (the physician who has been banned for life from cycling for his connection with various doping scandals) and is an abbreviation for the term "velocità ascensionale media" (or mean ascension speed in meters per hour). It is sensitive to slope: at the same power output, the VAM you can produce on a shallow slope is lower than the VAM you can produce on a steep one.

comment Should I let chronic training load drop (as in stop training) to end my current level of tiredness or continue riding?
The question doesn't give quite enough information to determine whether this is actually health-related or a result of training overload -- that's why I was asking for clarification. If the previous load was light then I agree it's health-related and would think it not in the purview of bicycles.stackexchange. If the load had been ramping up quickly then it could be a training question.

What kind of TSS were you carrying into the TT series, were your ATL and CTL changing rapidly, and what was your IF for the TT?

comment Does Bike or Rider Weight / Groupset affect cruising speed on the flat
Strava power estimates can be off by quite a bit (either high or low) when compared to actual measurements with an on-bike power meter, especially over short intervals. Averages over an entire ride will typically be closer. This could be a good bicycles.stackexchange question.

If you incorporate the clarification that a fluid trainer can produce the needed load but at high cadence rather than low, I would upvote your answer.

comment Trainers: Fluid or Mag
Here's an example: I just hopped on my CycleTek fluid trainer with my Power Tap-equipped bike. The trainer can handle 1000 watts but in my highest gear ratio (52x12) at 60 rpm my wheel speed was only ~31 km/h, and the trainer could only produce about 300 watts of resistance at that wheel speed. I would need a higher gear ratio to produce "high intensity" power at low cadence. The alternative, of course, is not to do this at low cadence. Many fluid trainers can produce adequate load if the wheel speed is high enough. That means high power at high cadence.

Right, the issue isn't whether there are trainers (either magnetic or fluid) that can create enough load -- the issue is whether they can create enough load at low rpm. "High intensity" usually means "sprint intervals" which are supra-VO2Max. In a sprint interval on the road your cadence is typically up around 120 rpm or higher and you're using a relatively low gear to accelerate up to speed. On a trainer the roller speed will need to be high, so you'll need to use a higher gear. You'll need an even higher gear still to do this at low rpm.

OK, thanks. The short answer is you're going to have a hard time finding a fluid trainer that will provide that kind of load at low rpm (and you won't be able to find a magnetic trainer that can provide that load at all). I'll do the calculations and provide a more complete answer tomorrow -- unless someone else wants to do the calculations and write-up and I'll upvote that.
